Kepler's Third Law of Planetary Motion gives the mathematical formula for this.
Isaac newton proved the Law follows from his theory of gravitation.
I will not go into the mathematics, but basically it's just how gravity works with planets.
It takes one year for Earth to orbit the sun. Other planets have different orbital periods depending on their distance from the sun.
The outer planets take longer to orbit the Sun, because they are farther away from the Sun. It make its gravitational pull weaker to the farther planets. That means that the outer planets take longer to orbit the Sun.
Planets further out from the sun have a larger orbit to travel around, which takes more time. This is because their orbital path is longer, meaning they move at a slower average speed compared to planets closer to the sun. This results in different orbital periods for different planets.
Well, basically different planets take longer to orbit the Sun. For example, Jupiter takes longer to orbit than earth, so Jupiter has a longer year. On Venus, a day lasts longer than a year as it takes longer to spin on its axis that to orbit the sun.
All those planets which lie outside (relative to the sun) earth's orbit will take longer than earth (1 year) to orbit the sun. Mars Jupiter Saturn Uranus Neptune
Planets do not take steps. Each planet has its own orbit and is is different.
Some planets rotate faster or than others. Also the planets take different times to orbit the Sun.
No. The planets all orbit the sun at the same time. The planets occupy different orbits at different distances from the sun so they do not affect one another significantly.

Halley's Comet takes 73.5 years to orbit the sun but every comet is different just like planets.
It takes one year for Earth to orbit the sun. Other planets have different orbital periods depending on their distance from the sun.
Moons are approximately spherical objects which orbit planets and are smaller than the planets that they orbit, although they are still relatively large objects (so an orbiting dust particle does not qualify as a moon). Since moons orbit planets, their motion around the solar system is controlled by the planets that they orbit; planets orbit the sun, and planets take their moons with them.
The planets in our solar system all orbit (revolve) around the sun on a plane called the ecliptic plane but each of their individual orbits has a different perimeter ranging from small (which would be the closest to the sun) to big (which would be further away from the sun). Since Mercury has the smallest perimeter of orbit, it is the closest planet to the sun and is thus more drawn by the suns gravitational force, both its small perimeter and strong gravitational pull make it revolve around the sun faster, and the bigger the planets orbital perimeter is the further away from the sun it is and the slower its orbit is.
"No"
they are farther away
The outer planets take longer.
